| ENS 47787 | 29 March 2012 21:20:00 | At the Browns Ferry Nuclear Power Plant (BFN), exclusion 'Red Zones' are established for compliance with the 20-foot separation requirements of Appendix R section III.G.2.b as modified by the associated NRC approved exemption for BFN issued on March 29, 2007. On March 28, 2012, it was determined that intervening combustible materials, i.e., cables, found in exclusion 'Red Zones' were not in conformance with Appendix R Section III.G.2.b and the associated NRC approved exemption issued for BFN. As a result of the intervening combustible material found in the exclusion 'Red Zones,' the degree of separation for redundant Appendix R safe shutdown trains is lacking. This condition is being reported pursuant to 10 CFR 50.72(b)(3)(ii)(B). Any event or condition that results in the nuclear power plant being in an unanalyzed condition that significantly degrades plant safety. The NRC Resident Inspector has been informed. |
